This invention relates to improvements'in more particularly to metallicwindow sash and frame construction, wherein the Isash swings outwardlyfrom within the frame. ..1 if" l y `The objectof theinventien is toprovide in awindow of theabove `described class, an improved sealedhinge joint between the parts, which' is dust, airA and waterproof, yetlpermittingy of free movement of the swinginor member or members. f f

` n carrying out my invention I provide, in a single sash construction,one side of the kwindow `frame witha unitary arcuate tongue extendingfrom top to bottom of said frame within thefsash opening, thusprovidinga semi-circular groove in which'the sash of the 'window pivots. In adoublesash Aconstructhe window frame are provided with grooved tonguesas will` be understood. f iy 'f One side of the window sash may beintegrally formed with'a bead and a curved wall spaced from the'bead toprovide lan f arcuate tongue yor extension on the window frame when-thesash swings outwardly 4with the bead as its center." The beadandarc.- uate chamber extend from bottom to top of the window sash. f j Theinvention possesses other advantageous features which will be setfforthat length in the followinfr'specifcation.

The arrangement o the partsmay be varied considerably, thepresentembodiment illustrates the inventionnow thought to be the bestform, k but yit will be understood that many refinements maybe marde inthe com-H mercial application construction provided yfor the purposeset' forth.

of brass, steel or other appropriate metal, wn or stamped to shape toprovide a rigid durable structure for use in connection withbanks,-oliice buildings, hotels and other kbuildings of the better sort.

Inv a single sash window construction I form a side rail 12 ofthe windowframe with ra unitary arcuate "tongue or extension y13,

providing a ling from top 1ng. f Y

vOne side or stile 15 of the window sash 11 'is preferably formed with aunitary bead 1.6, and an arcuate wall -17 spaced from said bead toprovide a chamber 18 adapted to receive the arcuate tongue 13, when thewinsemiscircular groove Mextend- ,to bottom of the window opening as thepivotal center.

The sill 19, ofthe window frame is preferably indented longitudinally toform a shallow groove 20, in which a stopbar 21, having' an upwardly disecured by screws or other devices 23.` n

The, lower rail 24 of the windowsash llhas formed therewith' adownwardly directed flange 25, which abuts the stop bar 21,'atritsyouter side when the window is closed, theV inner tace'of the ylower rail24 'also' abuts the flange 22-thus providing a sealed step joint at thebottom of the window Sash.

Lthe bead l 16v act-' rected flange 22 i. 'f

" 'Thestile 15 of the window is also formed` with a short outwardlyextending flange 26', which abuts the inner face of the window framewhen the window sash is closed. There is a space 27 provided between thewindow trame and sash, in which the'base plates 28, of brachets'i'orbracing the stile 15 may be disposedr and securedfto the 'window frameas'v shown in dotted `lines in section in Fig. 8. The brackets (but oneof which is shown)r take the form ofcurved with theirbase plates 28,

into` the curved chamber 118.'

` Base ypla tes 28, and thei-rlugs 29 may, how-v ever, be dispensed withsince the sash bead 16 could disengage its groove 14 in the arcuatetongue 13 in one position only, namely when the sash is fully closed. Topermit the 1 easy assembly of the window, I namely prefer to make thearcuate extension so that the circular bead could enter into'the same inthe position of the sash above men-v tioned, and naturally could also beeasily lift Fig. lL and in semicircular f ed out of it in said position.To prevent this I however' employed the abutting member 22 on the windowsill which will prevent the freeing ot the bead from the groove Vevenafter the arcuate tongue has left the cham ber 1S.

rl`he customary window panes 3l in place by appropiate means 32.

rIlhe terms and are held expressions employed, are used as terms otdescription and not of limitation, and I have no intention in the useott such terms and expressions ot excluding any equivalents ot thetentures shown.

Tha-t I claim as new is:

l. In a window, a trame and aV sash, the frame having a semicircularextension, the sash having means engaging said extension for impartingpivotal movement to said sash when it is moved outwardly, and a stopmember on the window iframe to prevent the disengagement ot the means onthe sash trom said extension when they are Jfacing the open side of saidsemicircle. l

2. In a window, a trame and a sash, the trame having a semioircularextensionproviding a groove, the sash having nieans engaging said groovefor imparting swinging movement to said sash when it is moved outwardly,and a stop member on the window trame to prevent the disengagement otthe means on the sash from said semi/circular groove when they tace theopen side ot it.

3. In a window, a traine and a sash, the frame having an arcuate tongueprovided with a semi-circular groove and extending from top to bottom etthe sash opening, the sash having means for engaging said groove toswing said sash outwardly, and a stop member on the window trame toprevent the disengagement ot the means on the sash from saidsemicircular groove when they face the open side of it.

4. In a window, a frame and a sash, the trame having an arcuatetonguepprovi'ded with a semi-circular groove and extending from top to.bottom 'et the sash opening, the sash having means for engaging saidgroove to swing saidsash outwardly, said means comprising a bead and anarcuate wall spaced therefrom, and a stop member onV the window trame toprevent the disengagement of the bead from said groove when inIiuxtaposition with the open side ot the semicircle.

5. In a metallic window, a frame and a sash, the frame having a unitaryarcuate tongue providing a semi-circular groove, the sash having aunitary bead adapted to enter said groove and an arcuate wall providinga chamber to receive said tongue as shown and described, and a stopmember on the window iframe to prevent the disengagement of the beadtrom said groove when in juxtaposition with the open side ot thesemicircle.

6. In a window, a tramev and sash, the frame having an arcuateextension, the sash having means engaging said extension impartingpivotal movement to saidy sash when it is moved outwardly, and bracingbrackets secured to the trame and entering openings in said sash.

trame having an arcuate extension providing a groove, the sash havingmeans engaging said groove tor imparting swinging movement to said sashwhen it is moved outwardly and bracing devices secured to the trame andentering openings in said sash.

8. In a window, a trame and a sash, the trame having an arcuate tongueprovided with a semi-circular groove and extending from top to bottom ofthe sash opening, the sash having means tor engaging said groove toswing said sash outwardly and bracing for y brackets secured to the'frame and entering I openings in said sash. A
